LLint should be able to use x87 instead of SSE for floating pointer

Reviewed by Filip Pizlo.

Implements LLInt floating point operations in x87, to ensure we support
x86 without SSE2.

X86 (except 64bit) now defaults to using x87 instructions in order to
support all 32bit x86 back to i686. The implementation uses the fucomi
instruction from i686 which sets the new minimum.
